Rock, Paper, Shotgun has a follow-up on recent reports of game bans in EA games resulting from forum activity. They have a statement from EA covering why players get banned, and their plan to reevaluate how this operates:

With every game and service EA offers, we take the satisfaction of our customers very seriously. We discourage cheating and strive to maintain a high level of integrity in both our games and our forums. Therefore when someone violates our Terms of Service, we are forced to take actions that can include suspensions and other measures. We do not take those decisions lightly – however the integrity of our services and the satisfaction of our customers requires a clear set of rules.

We have listened to our customers and are planning a policy update which will include more equitable rules on suspensions – we want to make sure the time fits the crime. As with all technology updates, these changes take some time to implement. Meanwhile, we urge any user with a question about suspensions or our policies to please contact us at (866) 543-5435 so we can address their specific situation.
